Magic Trackpad 2 support

Any plans to work on this driver further and especially support latest Apple hardware, like Magic Trackpad 2?

Freeze with ATP, Macbook Pro 2,1

I see that this was reported earlier this year, but the person who started the PR never followed up on the troubleshooting.

Symptom: After a few minutes, atp driver on older Macbook (vendor=0x05ac product=0x021a devclass=0x00 devsubclass=0x00 sernum="" release=0x0018 mode=host intclass=0x03 intsubclass=0x01 intprotocol=0x02) will become completely unresponsive. The issue appears to be calibration drift due to thermals in the Macbook. We all know the touchpads can drift significantly due to temperature changes and it would appear that the touchpad is not being recalibrated, thus causing the issue.

What is interesting is that as it becomes unresponsive, it appears as though the top of the touchpad fades first and slowly becomes unresponsive vertically, losing data output until the area of response finally reaches the bottom of the trackpad. Once the bottom goes away, there's no response at all so the miscalibration appears to be on the X axis over just a few minutes worth of temperature change.

Replacing the atp.c with the following date information:
__FBSDID("$FreeBSD: releng/10.1/sys/dev/usb/input/atp.c 263063 2014-03-12 07:15:41Z hselasky $");

With an earlier version from FreeBSD 10.0 release:
__FBSDID("$FreeBSD: release/10.0.0/sys/dev/usb/input/atp.c 233774 2012-04-02 10:50:42Z hselasky $");

... resolves the issue completely, but of course lacks all of the new, desired features. Given that there is such a great difference in code between the two, I don't know where to start troubleshooting but will be happy to assist.

Hope this helps to give you an idea of where the issue might be, saw that previous person's information and hope this helps to clarify a starting point. There's still a lot of these old Macs out there and would love to resolve this.

Thanks!
